Now that the show has aired on TV too, it’ a good time to reflect on some of the main themes of the series.

After all, we’ve got to time to kill as we wait for the next season.

Earlier this week, I interviewed the creators of the show, Michael DiMartino and Bryan Konietzko, and while they didn’t give me an air date for the next batch of episodes, they did break the news in our chat that Book 3 will be titled “Change.” They said that fans won’t have to wait as long for Book 3 to air as they did for Book 2.

They also told me that the name “Change,” like much of the series, was inspired by “Eastern philosophy.”
